Solutions
1) Find the least common denominator of 7/10 and 1/5.
10: 10
5 : 5 , 10
The least common denominator is 10.
2) Make the denominator of 1/5 to 10. Multiply numerator and denominator by 2.
1 x 2 = 2
5 x 2 = 10
3) New fraction
7/10 + 2/10
4) Add
7+2 = 9
9/10 is answer
9/10 can not be simplified. It is already in reduced form.
